Compute farm outage, Dec. 9-11

In order to upgrade the network connection between the compute farm and the central file systems, we will disable the GridEngine queues at 10 AM on Tuesday, December 9, to be re-enabled at 2 PM on Thursday, December 11. Please plan accordingly. Jobs that were started before the queues are paused on the 9th will be allowed to finish. Jobs that are waiting to start before the queues are paused, and jobs that are submitted while the queues are paused, will remain in the queues and will start on December 11. If you have any questions or concerns please submit a ServiceRequest.

[ Update, Dec. 9: Please note that this outage includes the interactive queues, so the qrsh command will be unavailable. ]

General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.

Unless other arrangements have been made, CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see SystemExpectations.
